I am Ko Jeong-wook, a representative children's literature author and self-proclaimed, widely recognized as Korea's greatest writer. I have published the most books among authors with over 350 volumes, received the love of 4.5 million readers, and travel the nation 365 days a year as a top-rated lecturer and writing judge. *Guide Dog Tansil*, *The Boy Who Carries the Bag*, *My Very Special Older Brother*, *The Grumpy Jaeseok*, *One-Line Writing Class a Day for Children*... Among my works loved by so many, *The Boy Who Carries the Bag* can be considered my representative masterpiece, even being included in elementary, middle, and high school textbooks. After studying in the science track through high school and switching to the humanities track for university, I realized that writing skills can grow significantly through effort and guidance. However, in the reality of our schools, there is no opportunity for our children to receive proper guidance on writing. Even teachers tend to focus only on proofreading and editing when asked to review their work. The best way to learn proper writing is from a writer like me who has extensive experience over a long period. I will guide my child to develop a hobby for writing, thereby observing objects with curiosity, learning patience and perseverance, and fostering original and sound thinking.
